Trifolium spp. are native plants in Iran exhibiting good ground cover po-tential. Salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. The main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...
Strawberry is considered as a salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. Pot experiments were conducted to determine the effect of exogenous salicylic acid (SA) application on physiology, growth, chlorophyll and mineral content of strawberry grown under salt stress and greenhouse conditions. Strawberry plants were treated wi...
in order to study the effects of different salinity levels on turnip (brassica rapa l.), an investigation was conducted at yasouj university, iran, in 2010. the effects of four salinity levels including 1.92, 9.87, 19.6 and 21.94 ds m-1 (20:1 ratio of nacl: cacl2 in hoagland solution) on germination, vegetative and maturity stages of turnip (baherghan landrace) were investigated. the results re...
Abstract Dorema ammoniacum is a medicinal plant, with plenty of chemical constituents, which has been used extensively in curing diseases. To study the salt tolerance of Dorema ammoniacum, its seedlings were put under different salinity treatments under hydroponic conditions. Dorema ammoniacum seeds were transferred to cold (4-5 °C) pretreatment for germination for 27 days. The germinated seed...
The Imam Khomeini sugarcane agro-industry is one of ten sugarcane agro-industry plantations in Khuzestan province. As regard as the drains has been installed in this plantation many years ago so there is water and salt balance in this land that is one of the condition for implementation controlled drainage. This research was designed to investigate the possibility of using a controlled drainag...
Predatory efficiency of Diplonychus rusticus (Fabricius) was recorded at different prey density with different salinity ranges. When the salinity level (ppt) was increased, the predation rate of the bug decreased. Fifth nymphal stage showed higher predation in the 2, 4 and 6 ppt levels of salinityin both 1 hr and 24 hr period of exposure at prey densities 50, 100, 150 and 200. At prey density 1...
Among abiotic stresses, soil and water salinity are the major factors affecting agricultural crops growth and productivity worldwide. On the other hand, the scion-rootstock combination and also foliar application of chimical compounds as salicylic acid can affect the nutrient elements content of almond leaf under salinity conditions. Therefore, in this study, the effects of foliar application o...
We tested the response of Enteromorpha intestinalis to fluctuating reduced salinity regimes which may occur in coastal estuaries due to both natural and anthropogenic influences. In a fully crossed two factor experiment, we subjected E. intestinalis to 0, 5, 15 and 25 psu water enriched with nutrients for 1-, 5-, 11- and 23-day periods. Each period was followed by 24 h of exposure to 25 psu (am...
Salinity is one of the most important environmental stresses that can affect crop yields. Identification of salt tolerant plants such as soybean, one of the most important oilseed crops, has a great importance. For this purpose, a factorial experiment in the completely randomized design with three replications was performed in the Sari Agricultural Sciences and Natural Resources University's gr...
A new split-root system was established through grafting to study cotton response to non-uniform salinity. Each root half was treated with either uniform (100/100 mM) or non-uniform NaCl concentrations (0/200 and 50/150 mM). In contrast to uniform control, non-uniform salinity treatment improved plant growth and water use, with more water absorbed from the non- and low salinity side. Non-unifor...
